3.3.1.1 Product Instruction
Storion-T50/T100-INV is a hybrid inverter. It has DC/DC and DC/AC modules. It can
transform the DC electricity from PV panels into three-phase AC electricity to supply
loads. The DC/DC module can charge batteries by using the electricity generated by PV
panels. The DC/AC module is bidirectional so that the battery can also be charged by the
grid through the inverter.
